SCALE- BEAM.

SPECIFICATION forming part of Letters Patent No. 232,393, datedSeptember 21, 1880, Application filed January 31, 1880.

To all whom it may concern:

Be it known that I, DANIEL W. DAKE, of Beloit, in the county of Rock andState of Wisconsin, have invented certain new and useful Improvements inBeam-Scales; and I hereby declare the following to be a full, clear, andexact description thereof, which will enable others skilled in the artto which my in-. vention appertains to make and use the same, referencebeing had to the accompauyingdrawings, forming a part hereof, and inwhich Figure 1 represents a side view of a beamscale embodying myinvention. Fig. 2 represents a side and end view of an adjustablesleeve, graduated in this example for the metric standard of weights;and Fig. 3 represents a modification of the sleeve B, adapted tofiatbeams of scales, in which B represents a side view, and B an endview, thereof.

My invention relates to that class of weighing-scales commonly known asbeam-scales and it consists in attaching to and upon the beam anadjustable sleeve having marked thereon one or more lines or scales ofdifferent systems or standards of weights, and so that the scale may bereadily changed from one system to another, substantially as hereinafterdescribed and claimed.

In the drawings, (0 represents the beam, as shown by dotted lines inFig. 1, of an ordinary beam-scale or steel yard, upon which is attacheda sleeve, B, gradnated,as shown, for avoirdupois weight, and upon whichslides the poise G, and at the end of the beam is hung the ma- 5 jorpoise D in the usual manner.

The sleeve B may also be marked with two or more different standards ofweight at different places along its length, so that any one of saidstandards may be used by turning the sleeve upon the beam to the desiredposition and substituting corresponding major weigh ts for those of D.

In the example of beam-scale shown the beam a, upon which the sleeve Bis adjustably fixed, consists of a round rod extending into thecounterpoisc E, and upon which is securely attached a short fixedsleeve, A, and upon said sleeve are attached the fulcrum and weighinghooks fand g in the usual manner. The counter-weight E is adjusted byturning it upon a scrcwthread out upon said rod.

The major weight is hung by a hook or loop, t', which is fastened to theend of the beam by a set-screw, l, and which also retains the sleeveupon the beam a in the desired position.

It is evident that the sleeve B may also be readily applied to the beamof platform or other beam scales.

I do not intend to limit my device to a round beam and correspondingsleeve, as the beam may be made in various forms that will admit of thesleeve being removed or adjusted upon the beam.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a beamscale, the beam a, having adj ustably attached thereon asleeve, B, provided with one or more scales or systems of weights,substantially as shown and described.

2. In a beam-scale, the beam to, having adjustably attached thereon asleeve, 13, provided with one or more scales or systems of weights, incombination with poise (3, loop 2', set-screw l, and major weights D,substantially as shown and described.
